To Eli:

By "non-ASCII" do you mean 8-bit characters?

There are wide equivalents of is* - isw*.

(I'm sure you know this already. I'm just a little unclear as to what you mean
above.)

To the OP:

If you're interested in the current state of play with regard to wide
characters, take a look at the DJGPP 2.04 C99 status page:
